Title: Suction device for internal combustion engine
Inventor: OKUMURA TAKESHI
IPC: F02B31/08
Filed: 1980-10-17
Abstract: PURPOSE: To obtain an adequate performance in a suction device for an internal combustion engine in each operating area in a suction air system having a helical main suction passage by providing sub suction passage of two systems having different hole positions for the main suction passage and selecting the respective sub suction passage in response to the engine operating conditions.  
     CONSTITUTION: An actuator 40 is operated by a control circuit 41 by a signal from a rotating speed sensor 43 at the time of rotating an engine at a low speed, and a switching valve 38 is switched to the position for communicating a branch tube 36 with the second sub suction passage 24b. In this manner the suction port 14 is imparted with a flow of a direction designated by an arrow b in addition to the suction air flowing in a direction designated by an arrow a through the port 14. Since this flow b has higher velocity than the flow a, the flow rate of the flow introduced into a vortex end 141 is accelerated, with the result that a swirl in a direction designated by an arrow c is strengthened. On the other hand, the valve 38 is reversely switched at the time of rotating the engine at high speed, the suction air from the tube 36 is introduced into the first sub suction passage 24a. This suction air flows in a direction designated by an arrow d, thereby weakening the swirl and introducing the suction air earlier to a combustion chamber.

Title: Stabilization circuit for characteristic of semiconductor laser diode
Inventor: YAMAGUCHI HIDEO
IPC: H01S5/042
Filed: 1982-08-20
Abstract: PURPOSE:To form a stabilization circuit for characteristics of a semiconductor laser diode with a simple structure by a method wherein the difference between the voltage which is proportional to a photo-current converted by a photo diode and the reference voltage is amplified, and the conduction current to an electron cooler which cools a laser vessel, and the laser bias current of the laser diode are controlled. CONSTITUTION:In a stabilization circuit for characteristic of a semiconductor laser diode, a conventional thermo-sensitive element is omitted so that an output of an error amplifier 7 is applied to a temperature controller 13 as the temperature measurements of a laser vessel 3. Since the bias current values I1, I2, and I3 for holding a light output at a constant value Lout correspond respectively to temperature T1, T2, and T3, the bias current values correspond to the laser diode 1, that is, the temperature measurements of the laser vessel 3. Meanwhile, since these bias current values are determined with the output of the error amplifier 7, as shown in the figure, inputting of the output of the error amplifier 7 to the temperature controller 3 is equivalent to applying the output of the conventional thermo-sensitive element.

Filed: 1977-12-05
Abstract: PURPOSE:To increase response speed and extend the life eliminating relay coils and contacts by halting the action of the triggering circuit simultaneously with lighting depending on the difference between the discharge starting voltage prior to the lighting of the discharge tube and the operating voltage after the lighting. CONSTITUTION:While a discharge tube is out of action, a constant voltage diode 22 conducts to charge a capacitor 24 and a trigger diode 25 is allowed to conduct, causing an instantaneous conduction of a thyristor 2. As a capacitor 29 charged by the power source 21 is discharged through at trigger transformer 30, a pulse voltage is induced on the secondary side of the transformer and applied on the discharge tube 20 through an external trigger terminal 31 to start discharge. In turn, the operating voltage falls leading the terminal voltage of the diode 22 to lower. Thus, the diode 22 is shut off the halt the action of the trigger diode 25.

Abstract: PURPOSE:To obtain constant sealability regardless of wear of a valve body by installing a sealing case onto a pipe passage with a tapered sealing hole and accommodating both a solenoid coil and a cone-shaped valve body nearly concentrically in this sealing case. CONSTITUTION:A pipe passage 1 with a tapered sealing hole 6 is provided with a sealing case 7 in such a manner that the case 7 surrounds the sealing hole 6. Inside this case 7, a solenoid coil 8 and a cone-shaped valve body 9 are accommodated nearly concentrically.
